Answer:

O Hooke and Leeuwenhoek

Explanation:

The scientists, O Hooke and Leeuwenhoek were prominent scientists. In fact, they are credited with being the pioneers of science especially the field of microorganisms. To be more specific, the two great scientists discovered what are known as protozoa. This was done specifically by Van Leeuwenhoek who discovered the single celled protozoa ,which were termed animalcules. In addition, the most prominent feature of the research and discovery was Leeuwenhoek's use of a self-designed microscope.

A volcano erupts and launches a chunk of hot magma horizontally with a speed of 252 m/s. The magma travels a horizontal distance

ArbitrLikvidat [17]

Answer:

The value is $v_y = -48.61 \ m/s$

Explanation:

From the question we are told that

The horizontal speed is $u_x = 252 \ m/s$

The horizontal distance is $d = 1250 \ m$

Generally the time taken by the hot magma in air before landing is mathematically represented as

$t = \frac{d}{u_x}$

=> $t = \frac{ 1250 }{252}$

=> $t = 4.96 \ s$

Generally the initial vertical velocity of the magma when it was lunched is

$u_y = 0 \ m/ s$

Then the final velocity of the magma when it hits the ground is mathematically represented s

$- v_y = u_y + gt$

Here the negative sign mean that the direction of the velocity is towards the negative y -axis

$- v_y = 48.61 \ m/s$

=> $v_y = -48.61 \ m/s$

What is the mechanism of hydraulic machine

nata0808 [166]

Answer:

The hydraulic press allows the applied force (F1) to be converted into a higher force (F2) along some path as many times as the surface of the driven hydraulic cylinder (A2) is larger than the surface of the driving hydraulic cylinder (A1). The hydraulic press works on the basis of Pascal's law, which reads: External pressure is transmitted through the fluids equally in all directions.
